Disclosed herein are techniques to enable remote wakeup of controlled devices. In particular, a controlling device and a controlled device may each power on a radio during a wakeup window. The controlling device may communicate a wakeup frame to the controlled device during the wakeup window to wake the controlled device from a sleep or low power state for purposes of communicating with the controlled device in a network, such as a peer-to-peer network. 本文公开了能够实现控制设备的远程唤醒的技术。具体的，控制设备和受控设备每个可在唤醒窗口期间使无线电通电。为了在诸如对等网络的网络中与受控设备进行通信的目的，控制设备可在所述唤醒窗口期间将唤醒帧传送至所述受控设备以将所述受控设备从睡眠状态或低功率状态中唤醒。
